Great value!!

Love this speaker. I had a UE Boom that was much more money that worked well so decided to give this a shot due to its price and it exceeded my expectations. I love the fact that once you turn it on, it automatically goes into paring mode. I tried it with my fire stick and watched the entire ufc 252 ppv with no battery or sound issues. I then streamed music while working al day today and it finally needed a charge after about 12+ hours of use! Highly impressed.

This speaker is just a little longer than my phone and is a little heavy but the sound quality on this is by fair anything but small. When I first tried this out and connected it to my phone, it was already turned up but it wasn't even close of being all the way turned up. When it comes to connecting, as long as you have it connecting to the right speaker, it connects easily and even chimes when it's connected to your device. The volume is easy to turn on and off but with the play button, this gives you the option to either play whatever you are listening to or you can press it again and it'll pause. Charging it doesn't take long. I always charge my devices before actually using them and this did come with a slight charge but was not 100%. It didn't take long to charge it but even when this does need to be charged, it never takes that long to charge it. We've used this speaker to listen to music or even watch a movie from our projector. While it's just us watching a movie from the pool, we have our setup about 10-12ft away and our neighbors have said they can clearly hear watch kid movie we're watching. The sound quality is amazing on this and love that it's a Type C cord since our phones are the same type. It does come with a D ring and there is a small tab that you hook that on to. Easy to hold and easy to use speaker. Quality made and the sound is phenomenal.
